Houston is waking up Saturday, August 15, to clear skies, sticky air and temperatures around 81 degrees. The heat will build quickly, with a sunny afternoon high near 96 and a heat index reaching 106. Rain will be hard to find, setting up a long, hot stretch across the city.
Sunny Saturday Brings Dangerous Afternoon Heat
Saturday’s forecast calls for mostly sunny skies, a southerly breeze and only a 5% chance of rain, according to the National Weather Service. Temperatures should climb through the 80s during the morning before reaching the mid-90s in the afternoon, when outdoor work and exercise will feel especially taxing.
Saturday night will stay mostly clear but warm, with a low around 77 degrees. No watches, warnings or advisories are listed, but heat-sensitive residents, outdoor workers, children and pets should still be treated as at risk during the hottest part of the day.
Upper-90s Heat Lingers Into Next Week
Sunday through Thursday will bring more sunshine and highs between 97 and 98 degrees, with overnight lows mostly in the upper 70s. The broader Houston-Galveston forecast calls for a nearly rain-free pattern through much of next week, while inland areas could occasionally approach 100 degrees.
Friday offers the first small break from the dry pattern, with a slight chance of showers and thunderstorms after 1 p.m. The rain chance is just 15%, so most plans should remain dry, but a few afternoon storms could finally interrupt the week’s relentless sunshine.
Small Heat-Safety Steps Matter
Drink water before you feel thirsty, take frequent breaks in air conditioning or shade, and choose loose, light-colored clothing for time outside. The Houston Fire Department also reminds residents to check vehicles before locking them and never leave children or pets unattended inside.
